Formula for 5G NR ARFCN

The formula for 5G NR ARFCN is described in 3GPP TS 38.104 chapter 5.4.2.1.

Frequency is selected from 3GPP TS 38.104 Table 5.4.2.1-1

Frequency range (MHz)	ΔFGlobal (kHz)	FREF-Offs (MHz)	NREF-Offs	Range of NREF
0 – 3000	5	0	0	0 – 599999
3000 – 24250	15	3000	600000	600000 – 2016666
24250 – 100000	60	24250.08	2016667	2016667 – 3279165

By default, frequency range of 5G NR is divide into two parts FR1 and FR2 (below you can see table from 3GPP 38.104, table 5.1-1).

Frequency range designation	Corresponding frequency range
FR1	450 MHz – 6000 MHz
FR2	24250 MHz – 52600 MHz
